Barrow, Alaska: A remote, isolated town that is plunged into a state of complete darkness for 30 days every winter. It is here that a group of marauding, merciless and bloodthirsty vampires, led by Marlow (Danny Huston), are coming. Their intention? A month long, uninterrupted feast of its helpless residents. It is up to Sheriff Eben (Josh Hartnett), his estranged wife, Stella (Melissa George), and an ever-shrinking group of survivors to do anything and everything they can to last till daylight.
